[TYPES] Best pedagogical presentation of CPS?

Amr Sabry and I were the first to show that CPS is sound and complete with
a reduction semantics. Sabry and Felleisen had previously shown a
translation sound and complete with equational semantics.
A reflection on call-by-value
Amr Sabry and Philip Wadler. ACM Transactions on Programming Langaguage,
19(6):916-941, November 1997.
The results are, to my mind, surprisingly straightforward, with the tricky
part being to get the source and target calculi and the administrative
Plotkin showed soundness but not completeness. When I presented these
results at Edinburgh (long before I moved there), Plotkin was in the
audience. With some trepidation, I said, "I believe this improves on your
result of twenty years ago." Gordon immediately responded, "Yes, but you've
had twenty years!"
